vThis .invention iis 4for 1a. copingfor use on the parapet walls ofbuildings and4 like places lwhere it is desired to preventfwater irom'soaking-.down into the wall, and is :designed to rerace the usualcoping stone which Ais quite commonly used, and to eliminateth'e needfor'through wallv flashing bel'ow the coping stone.

Where a coping vstone `is"fused on `top of -a parapet wall, vforexample, itis the nsual practice to put a throughV wall ashin'gfon thetopcf the wall below the 'coping to exclude the .seepage `.of 'waterdownwardly through the wall. Sometimes the hashing is not used, in whichcase the `masonry is relied'upon'to-'effectasuincient'stoppage;againstpenetration, -but this vcommonly `results in water seeping through thewalland leaching out -lime from the mortar, leaving Ia discoloration onthe face of the building. It has been lproposed in cheaper constructions'to carry the roong up the interior face `of the parapet wall and overthe top of the parapet,v using Atar and Toon-ng. paper, but thisdetracts from the appearance of the wall, adds to the fire hazard,andina'y Vbe loosened by freezing weather-or high winds.

The object o'f the :present invention-is to provide a metal coping whichfis architectural'ly pleasing, which effectively excludes moisture fromthe top of the masonry -or fparapet fwall, and 'which will endure forthe life -of the metal `from lwhich it-s made. The copinglbrie-yreplaces the need for any through wall flashing.

My invention/may `rbe more fully understood by reference to theyacconflpan'yin'g drawings, in which:

v1fis-a perspective view of a corner of a parapet wall having my Tcopingapplied thereto;

Fig. 2 :is -a transverse section -in the plane of line II-II of Fig.11;. and

Fig. 3 isa vertical section `longitudinalh7 offa portion or the parapetwall, the view being in the plan'e'of line IzII-III'of Fig.` 2.

According to `the present.l invention, the Vlaarapet wall or othermasonry Jover which the Scoping is to be placed, and which isdesignate'd2, is laid with embedded threadedrstudsorbelts 3 therein atre'gularintervals, 'the threaded ends o'f `these bolts projecting beyond thevtop ci the masonry. The bolts are preferably placed "aifong thelongitudinal center line of the building, vandthel space is ratheraccurately predetermined'.

These belts serve 'te anchor Ithe lcoping to the masonry. The copinginclud'esa transverse Ichannel "4 formed preferably troni "sheet metal,Ythe channel being generally iU-shape'd in transverse Section,is"best"Sheff/viriF'ig. 3. Il? hais a bUltO'm' 5, the center ofwhichis'lraised to providey a ridge 6,?and'through thetop of thisridgethere is a `hole -1 to acccm'mod'ate the upper end of the rstud 3. One'of these channels is provided at each point where there Vis one of .theembedded bolts. The channel llasside flanges 8, and these flanges, asbest seen in Fig. 2, rtaper in height from the inner face :2a of thelparapet wal-1, having a height at the inner endl ofthe channel slightlygreater than the height 'of the rib f5, while being somewhat higher at'that end yof the channel lwhich is 'adjacent the outerv edge `of thepara-'pet wall. In the drawings, 2a `designates -the inner faceof theparapet wall, and l'2b :designates the outer face. The "bol-t 3 passesup through the hole 'l :in the ridge at the base -fof `the channel, anda nut 3a is screwed thereon to 'an'chor the channel to 'the masonry. Ateach side of thestudfB Ithe channel is provided with fa threaded openingil, these openings l9 also being made in the topof the ridge 6 in thebottom of the 'channel` f AThe end of the channel "at theouter face Aofthe Wall is 'curved upwardly, as indicated at 5a, and the end of vthechannel Aat the inner face 0f the wall is turned downwardly as indicatedat 5b.

The main bodycf the coping is formedof metal sheets lll outtothe'properlength. The sheets H) have a wide, downWardlyLtu-rned flangeII at the outer face thereof, and the lower 'edge of thisangeturns'inwardly providing a lip `I2 that terminates clc'se'tothecuterfaceof the parapetwall. The vinner edge 'of thesheet- I 0 is bentdownwardly, providing la depending ange |3. In Fig. 1 I have shown 'thestructure at the corner of the building where two of fthe :members IUare miter-'cut and solderedl or otherwise .icined together, butthroughout the greater Yportion of the length of the wall, the sheets'are of course straight. The endso'f the sheets lfoverhang 'the il'anges8 of the channels f4. as best shown in Fig. 3, and these over-hangingledges `cf the ends are bent downwardly as indicated at I0 in Fig. '3 tomore effectively make a weather-tight joint with the channel. An capstrip |4 which is more than twice as Wide fasfthe channel il, is placedover the top of the -channel 4 after the ends have vbeen bent downwardlyas indicated at VIll in Fig. 3. This cap strip has holes thereinpositioned so that screws I5 passing through the cover strip will enterand be screwed into the holes `El in the bottom ridge `ci the channel.The cover strip I4 thus serves to form "a lap Ajoint between the vendsof the tw'o sheetsy IIJ, and it also 'clamps the ends of the sheetagainst the flanges 8 of the channels 4.

In "assembling, 'the wall is prepared to receive the coping by embeddingthe bolts therein. The channels 4 are then secured in place in themanner hereinbefore indicated by the studs 3 and nuts 3a. The copingsheets I0, which have previously been bent to form, and which are cut tothe required lengths and otherwise prepared for the job, are then laidin position. As each two sheets are put in place, the cap strip I4 isscrewed down. The cap strip I4 has a downwardly-turned flange I6 at thefront face of the building that is turned inwardly to hook around thelip I2, and it has a downwardly-turned flange I'I at its inner end whichis curled up under the iiange I3 of the ends of the two sheets I0 whichit overlaps, as best shown in Fig. 2. This serves to more securely jointhe coping sheets to the cap strips, which cap strips are invturnsecured to the cross channels.

The taper on the iianges 8 of the cross channel imparts a slope to thetop of the coping so that the front or outer edge of the coping ishigher than the inner edge. This results in any water falling on thecoping draining back onto the roof of the building, instead of fallingdown the front of the building. The cap strip serves to prevent theleakage of any substantial amount of water adjacent the ends of thesheets I0, but if any water does drive under the cap strip I4, it willflow down the sloped ends I0 of the sheets and drip into the bottom ofthe channel 4. The ridge 5 at the bottom of the channel in which thebolt and screwed holes are made is above the level vof any water whichwould thus seep into the channel. Any water thus collected in thechannel cannot flow down the front of the building, due to theupwardly-turned apron 5a. Such water drains to the back of the wall andflows down the downwardly-turned edge of the channel 5b to drip downonto the roof. Should the screws I5 not be entirely tight, so that watercould seep in around them, of which there is only a slight possibility,such water would run down the shanks of the screws I5 and drain from theshanks of the screws down the ridge into the bottom of the trough.

` The channels 4 are at reasonably close intervals, determined by thesize of the sheets which itis practical to handle, but the best spacingcan be determined by the roofer. Excessive distance between channelswould permit undesirable sagging of the sheets I0. There is suilicientventilation under the coping to allow for breathingf and the evaporationof moisture or elimination of condensate. The coping provides a pleasingand attractive trim' or nish, and is as enduring as the metal of whichit is made. It is less expensive than stone, and of course flashingunder the coping is not required.
